can PgMP & PfMP be qualification for Politicians and Administrators?

This is can be looked at from many angles. Rephrasing what Kiron said, those certifications would be an asset for senior leadership roles in developing and implementing effective policies and national development programs. Although from my perspective it would not be sufficient.

Coming from a country that has severe difficulties in making laws, maintaining laws, and providing viable solutions to humanitarian issues.

If the end goal is better governance there would be a requirement to make sustainable changes to the current bureautic system and remove the abundance of red tape. It is common for those in the senior positions and administrator positions to have a variety of skills and competencies but lack the needed legroom due to archaic systems and processes. Due to this, the government is always slow to change.

Moreover, you would also have to consider the element of rampant corruption and nepotism. I firmly believe there are already viable solutions but due to the "big man" policy followed by those at the top. What is actually needed is scrap in favor of things that fit their own bias and preferences. Even if it will not bring any value in the long term. Within the political landscape, there are far too many grey areas, and implementing what is actually needed versus what is actually done always leaves more questions. Regardless, the state of governance from public servants would require an array of feasible methods in order to improve overall governance. Additionally, it can not be done in an instant or simply upskilling public servants.
